System Boots From the Wrong Device

Problem: Your system is supposed to boot from the disk; instead, it boots from the net.

There are two possible causes for this:

• The diag-switch? NVRAM parameter is inadvertently set to true.

Interrupt the booting process with Stop-A. Type the following commands at the ok prompt:

ok setenv diag-switch? false 
ok boot 

The system should now start booting from the disk.

• The boot-device NVRAM parameter is set to net instead of disk.

Interrupt the booting process with Stop-A. Type the following commands at the ok prompt:

ok setenv boot-device disk 
ok boot 

Note that the preceding commands cause the system to boot from the disk defined as disk (target 3) in the device aliases list. If you want to boot from disk1 (target 1), disk2 (target 2), or disk3 (target 3), set boot-device accordingly.

Problem: Your system is booting from a disk instead of from the net.

• boot-device is not set to net.

Interrupt the booting process with Stop-A. Type the following commands at the ok prompt:

ok setenv boot-device net 
ok boot 

Problem: Your system is booting from the wrong disk. (For example, you have more than one disk in your system. You want the system to boot from disk2, but the system is booting from disk1 instead.)

• boot-device is not set to the correct disk.

Interrupt the booting process with Stop-A. Type the following commands at the ok prompt:

ok setenv boot-device disk2 
ok boot
